Vertical Integration Into Substrate Becomes The Real Strategy
Substrate is roughly 47% of finished silicon carbide device cost and crystal growth takes seven to 14 days that no capital expenditure shortens, which makes wafer supply the binding constraint rather than fabrication capacity. Every serious participant has responded by buying crystal growers, signing multi-year substrate agreements, or building boule capacity outright. The 200 millimetre transition raises the stakes further, since larger diameter improves device economics considerably while making defect-free growth harder. Device design differentiation matters far less than this. Nobody is winning this on device architecture any more at all.
